Abstract

The apparatus comprises a mixing chamber (18) and a screw means 15, disposed within the chamber (18), for mixing and transporting material downstream to an air atomization nozzle (51). Another aspect of this invention is a method for mixing and spraying a slurry. The method comprises introducing and propelling a particulate solid along a mixing chamber (18). A liquid is introduced downstream from the introduction of the solid, a sufficient distance such that no substantial liquid backs up to the introduction of the solid. The solid and liquid are mixed to form a slurry, substantially in the absence of air. The slurry is propelled downstream, substantially in the absence of air, and atomized. <IMAGE>
